Abstract

Background: Oral treatments for diabetes mellitus (DM) may have a deleterious effect on acute coronary syndromes (ACS) outcomes. Aim: We aimed to examine in-hospital mortality among patients with ACS and DM and the Impact of anti-DM treatment modalities. Methods and results: The Euro Heart Survey ACS prospectively enrolled 10484 patients across Europe and the Mediterranean basin. Of the 10214 patients with recorded DM status, 2352 (23.0%) had DM, of whom 562 were on diet alone, 1112 received oral hypoglycaemics, 561 received insulin, and 117 received both. The in-hospital mortality for ST-elevation-ACS was 9.8 and 5.7% for patients with and without DM, respectively, with an adjusted risk (95% confidence interval) of in-hospital mortality of 1.6 (1.2, 2.1). The in-hospital mortality for non-ST-elevation-ACS was 2.8 and 2.0%, accordingly, with an adjusted risk (95% confidence interval) of in-hospital mortality of 1.2 (0.8,1.9). The in-hospital mortality for undetermined-electrocardiographic- pattern-ACS was 11.5 and 10.9%, accordingly, with an adjusted risk of in-hospital mortality of 1.1 (0.6, 2.0). Among DM patients with ST-elevation-ACS, the adjusted risks of in-hospital mortality were 1.0 for diet therapy, 0.8 (0.4, 1.5) for oral hypoglycaemics, and 1.9 (1.0, 3.8) for insulin; for DM patients and non-ST-elevation-ACS, 1.0 for diet therapy, 2.2 (0.6, 78) for oral hypoglycaemics, and 3.5 (1.0, 12.5) for insulin; for DM patients and undetermined-electrocardiographic-pattern-ACS, the adjusted risks of in-hospital mortality were 1.0 for diet therapy, 0.9 (0.2, 4.6) for oral hypoglycaemlcs, and 2.1 (0.5, 9.5) for insulin. Conclusions: Acute coronary syndrome patients with DM, especially those with ST-elevation, had increased in-hospital mortality. Among ACS patients with DM, those receiving insulin had worse outcomes. Outcomes were similar for those on hypoglycaemics or on diet alone.
